Question

Why do we easily slip on a rainy day? Explain.

Answer 1

Hint:Here in order to answer the question we will first clear our concept related to friction and its types and then we will answer the question why friction is less on rainy days.

Complete answer:
Friction is known as the force that prevents one solid object from moving over another. Static friction, sliding friction, rolling friction, and fluid friction are the four major forms of friction. Friction and normal force are proportional to the touching surfaces and are independent of the contacting surface's hardness.

The following are some static friction examples: When you're skiing against the snow, it's a lot of fun. By rubbing both hands together, you can generate heat. On the table, there is a table lamp.
The examples of sliding friction are as follows: A block slides across the board, and two cards in a deck slide toward each other.
The examples of rolling friction are as follows: The rolling of a log on the ground, as well as the wheels of moving vehicles.
Fluid friction can be seen in the following examples: The ink in pens is floating around.We are more likely to fall on rainy days because rainwater serves as a lubricant between our feet and the ground. The rainwater lubricates the dry friction, converting it to fluid friction. As a result, the tension between our feet and the ground decreases, causing us to fall.

Note: Sliding friction decreases as relative speeds increase, while fluid friction increases as relative speeds increase. Fluid friction is often affected by the viscosity of the fluid. Since there is no water serving as a lubricant on a dry day, friction is preserved, preventing us from slipping.
